Tl RE-SETTING APPARATUS SPECIFICATION forming part of Letters Patent No.301,371, dated July 1, 1884.

Application filed November 9, IRE-3. (No model.)

To aZZ whom, it may cncern:

Be it known that I, Josnri-r Jones, of Springfield, in the county ofClark and State of Ohio, have invented certain Improvements inTire-Setters, of which the following is a specification.

This invention relates to apparatus for setting tires on wheels, and forproducing, modifying, or removing the dish, as required.

The invention consists in an annular bed to support the felly, a seriesof levers of peculiar construction jointed or pivoted thereto at regularintervals, and provided with hooks or claws to engage over the tire, anda central disk above the table or bed, provided with an elevating anddepressing screw, by which it may bemade' to bear with any desiredpressme upon the hub of a wheel upon said bed, whether the disk be usedwith or independently of the levers.

In the accompanying drawings, Figure l 1 represents a perspective viewof my improved machine or apparatus; Fig. 2, a vertical centralsectional view of the same.

Thepresentinvention is designed,primarily, to supersede the common modeof setting tires merely by the aid of hand-tongs, which plan is at onceuncertain and difficult of application, requiring skill and familiaritywith the work, and often involving considerable injury of the fellywhere such skill or care is lacking. lVith this purpose in view Iconstruct the apparatus in the following manner, referring again to thedrawings for illustration of the parts described.

A indicates a strong wooden frame, consisting of two uprights, ac, and atop cross-piece, Z2, firmly joined together in any convenient manner. Ata suitable height within said frame or between the posts a a is placed ahorizontal annular bed or table, 13, of metal, usually about five or sixinches in width" all around, and of a diameter suited to receive andsupport wheels of all ordinary sizes, though it is of course obviousthat difierent machines may be provided to accommodate difl'erent'sizedwheels where the variation is great. One machine will ordinarily answerall requirements, however. The bed or table B is sustained by the postsor uprights a a, and also by legs a c, or in any other convenientmanner.

C G G indicate levers, of which I preferably use three, as shown,arranged radially and equidistant from each other about the table.

These levers O are each composed of twoparts, (Z and 6, connected bylinks f, asshown, so that one partmay move longitudinally in relation tothe other. The memberdis made long and fashioned into a hand-lever, asindicated, while the member 6 is shorter, extends slightly beyondtheinner end of hand-section d, and has said projecting end jointed to aneye or lug, g, at the lower side of the bed or table, B, as shown. Thejoint h forms a pivot or center of motion about which the lever O, as awhole, may be raised or lowered, and the links f permit the hand-sectiond to be moved longitudinally in or out toward or away from the bed ortable. Each lever G is furnished with a hook or claw, D, forked atoneend to straddle the lever, and pivoted thereto advisably at a pointbetween the links f, as shown. These hooks or claws serve to engage overthe tire and to draw it both outward and downward over the felly of awheel placed upon the bed or table, as will be readily understood fromthe drawings. By reason of the endwise movement of the hand-pieces d ofthe levers G, and the consequent endwise movement of said sections andthe hooks they carry, the hooks and levers may be instantly adjusted tosuit wheels and tires of different diameters.

In fact, they will automatically adjust themselves thereto, thus givingthe machine a wide range of use. The levers permit a great amount offorce to be applied when necessary,

yet may be operated with as slight force as desired; but in any case thepower is applied in the proper direction with the utmost certainty andease.

In applying tires to wheels it is often found necessary to give them agreater amount of dish or depression at the center than is found in themwhen handed over to the smith for the application of the tire, or tolessen the dish, or in some cases to remove the dish entirely. This, tobe done effectually and to re main permanently done, must be done at thetime the tire is applied, in order that the tire may be shrunk on withthe wheel in the de' sired shape, and thus made to bind and hold it insuch shape. I therefore provide at the top of the frame A a metal yoke,E, having a central threaded hole to receive a vertical screw-stem, F,which carries at its lower end a broad, fiat disk, G, and at aconvenient height above the disk a hand-wheel, H, by which the screw maybe rotated to cause the raising or lowering of the disk. The wheel beingsustained by the bed or table B beneath its fel'ly, but unsupported atits center, may be given any required degree of dish by forcing down thedisk upon the hub of the wheel through the turning of the screw, thedisk being advisably held firmly against the hub during the applicationand until after the shrink ing of the'tire upon the felly.

If it be desired to lessen or remove the dish. of a wheel, the raisedcenter is placed uppermost and the pressure applied as before.

I am aware that a lever provided with a hook to engage over the tire andto draw the latter down upon the felly of a wheel is not new in and ofitself; but I am not aware that any one has ever before constructed thelevers in the manner herein described, or arranged them or otherparts'to operate as herein set forth.

I am further aware that a tire-setting device has been provided with acentral screwstem or spindle to pass through the hub of the wheel, andwith nuts to bear against the ends of the hub to produce the desireddish and retain the same during the cooling of the tire. This I do notclaim. My plan differs from the above in that the disk bears onlyagainst one end of the hub; that the spindle does not pass through thehub, and that it is 'not necessary to first remove a nut before thewheel can be removed, or to adjust two nuts inorder to regulate thedish.

Having thus described my invention, what I- claim is 1. In atire-setting machine, in combination with a supporting-bed having anopen center, a series of radial levers, each provided with a hook orclaw projecting inward over the bed and pivoted to said bed,substantially as shown and described.

2. In a tire-settingv machine, in combination with a supporting-bed, B,having an open center, radial levers 0, consisting of parallel parts dand 6, connected by links, one of said parts being pivoted to the bed,substantially as explained, and hooks D, applied to said levers andprojecting inwardover the bed, as and for the purpose explained.

3. In a tire-setting machine, in combination with an annularsupporting-bed, a central screw-stem wholly above the same, providedwith a disk at its lower end, adapted to be forced downward toward theopen-center of the bed, substantially as set forth.

4. The herein-described apparatus for producing the proper dish of andapplying tires to wheels, consisting of frame A, annular bed B, compoundlevers O, jointed or pivoted to said bed and provided with hooks D, yokeE, screw-stem F, and disk G, and hand-wheel H, applied to saidscrew-stem, all substantially as shown and described.
